I've had the following STI part list in my emails for so long now and have always forgot to share it to the forum. The majority of people would already know about these items but what I've got is the full list of domestic STI parts for the Liberty available from a Subaru dealership throughout Australia; it does not include anything from abroad.
Prices were quoted to me in 2013 for your reference. If there are any discrepancies please don't hesitate to let me know and I'll edit the list accordingly.
There were initially links for the parts too but they've since broken so I won't bother adding them in.
